Castelli Free 6 Sock

The Castelli Free 6 sock uses a 6 inch cuff which is what we consider a traditional length cuff. When Castelli uses the word Free in their product description, it usually means that the product is a simple design with a free and non-restrictive nature. In this case, the Free Sock is a simple design with a full vented body and just a single compression strap that wraps the instep. One of our better selling socks, the Free Sock feels like a natural extension of your foot.

The entire sock body is constructed of Meryl Skinlife fabrics which does a great job at wicking moisture away from your foot while providing plenty of breathability and air flow. The top of the instep has a diaphanous web knit, meaning it is thin, light and airy, while the rest of the sock has a slightly thicker blend for a bit more support. Choose size and color.
